What is the domain for the following function?

Mathematics
1 answer:
sammy [17]4 years ago
3 0

Answer:

it's B

Step-by-step explanation:

the set of numbers for which a function is defined is called a domain of a function

if a number is not in the domain of a function, then the function is undefined for that number

denominator must not be zero

if we plug -3 then the y

=(-3+1)/(9+-3-6)

=(-2)/9-9

=-2/0

which is undefined for x=-3

now

if we plug 2 we have

(2+1)/(4+2-6)

=3/0

the function is undefined for x=2

so

x≠3, x≠2

15) Bob has 12 black pen, 14 red pen, 15 green pens, 24 blue pens and 3 boxes of
cricket20 [7]

Answer:

13, 16, 18

Step-by-step explanation:

Sabemos que podemos calcular el total de plumas amarillos, por medio de la media.

16 = (12 + 14 + 15 + 24 + x + y + z) / 7

16 * 7 = 12 + 14 + 15 + 24 + x + y + z

112 = 65 + x + y + z

x + y + z = 112-65

x + y + z = 47

sabemos que la mediana es el valor medio, y que ese 46 debe dividirse entre 3 valores porque son 3 cajas, entonces debemos buscar los números adecuados para el valor 15 esté en la mitad, es decir de cuarto.

Sin meter los valores nuevos, el ranking sería así:

12

14

15

24

el 15 esta de tercero, para que quede de cuarto, debe tener dos valores por debajo y un por arriba, así:

X

12

14

15

y

z

24

Por lo tanto, valores mayores a 15 serían por ejemplo y = 16 y z = 18:

16 + 18 = 34

x = 47-34 = 13

quedaría:

12

13

14

15

dieciséis

18 años

24

Si recalculamos la media:

m = (12 + 14 + 15 + 24 + 13 + 16 + 18) / 7 = 16

Find exact length of the third side
vodomira [7]

Answer:

37

Step-by-step explanation:

This is a right triangle so we can find the lengths by using the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

12^2 + 35^2 = c^2

144 +1225 = c^2

1369 = c^2

Take the square root of each side

sqrt(1369) = sqrt(c^2)

37 =c
